Cisco Certified Network Professional Practice Test

The correct answer is based on the standard configuration for Active Virtual Forwarder (AVF) timeout periods in Cisco networking environments. The default timeout period for declaring a failed AVF as dead is indeed 14,400 seconds, which translates to 4 hours. This duration allows the network to maintain normal operations and reliability during transient failures while also ensuring that the forwarding roles can transition effectively if an AVF becomes unresponsive for a significant length of time. Understanding this value is essential for network engineers focusing on high availability and resilience. The extended timeout period helps to avoid unnecessary failover in cases where an AVF might briefly lose connectivity or experience a momentary disruption. A shorter timeout could lead to frequent failovers, causing instability and performance issues in the network. Therefore, the 14,400 seconds buffer is designed to balance responsiveness with system stability.
